AMD-Pstate Driver Updated A 5th Time For Improving Ryzen Power Efficiency On Linux - Phoronix
Sent out today was the fifth revision to AMD's new "amd-pstate" kernel driver focused on providing enhanced CPU frequency controls for Linux systems.
AMD's P-State driver remains under active development for improving the Linux power efficiency for Ryzen (and EPYC) processors. AMD P-State makes use of ACPI CPPC for more informed and finer-grained frequency controls on modern (Zen 2 and newer) processors compared to what is afforded by the existing ACPI CPUFreq frequency scaling driver currently used by AMD Linux systems.
